Soooo masks work?

In the controlled hospital setting yes, because at most hospitals all employees are now wearing masks and we can localize the patients with COVID-19.

Among the general population, decades of data from around the world shows you need at least around 80% of the population wearing masks at all times when out in public to decrease the vital burden enough to in and of itself limit spread.

Again, regular surgical masks don’t protect you. They protect others from you, and so enough people have to wear them to remove most environmental virus in the air and on fomites to actually grant protection to everyone.
